The invention is shown as applied to a machine similar to that disclosed in United States Patent No. 1,932,013, issued October 24, 1933 to Loring P. Crosman, and entitled Registers. The printing mechanism illustrated forms the subject matter of an application for patent, Serial Number 421,015, filed of even date herewith.

In accordance with this disclosure, amounts set up in the digit keys 2l5 (Fig. 1) are transferred to an accumulator -413, upon operation of the machine, by means of a series of differential actuators 6l0. These differential actuators are spring operated, and are normally restrained by frame 6l6. Actuators 6|0 are formed as threearmed levers. theforward arms thereof having segmental gear teeth for rotating the accumulator wheels; the upper arms being pivotally connected each with a rearward arms being pivotally connected each with a type bar 6H of the printing mechanism. The actuators 6l0 are normally held under restraint of a series of zero latches 2f 4, each zero the operation key elevation of a portion digit index bar H5, and the latch being releasable upon depression of any key M5 in the same column by means of a slide 2l3. Upon operation of the machine, and movement of frame BIG, the released actuators will be rotated counter-clockwise until stopped by contact of a lug of the related index bar 6l5 with the stern of the depressed key, thereby registering the value of said key in the related accumulator wheel and setting the type bar 6 into position to print the digit. Addition Addition is effected by the depression of a motor key H4 (Fig. 2), the stem of which is provided with a cam surface 40, acting in the depression of the key to move "a slide 4| forwardly, thereby operating a bell crank lever 42 having a roller 43 engaging a notch formed in a spring operated slide 44, illustrated also in Figs. 3 and 4. Slide 44 is provided with a lug 45, which, upon depression of key I I4 and operation of slide 44, will engage with the upper arm of a pivoted latch H2, thereby releasing the clutch control lever i06 from said latch, whereupon said lever will be moved counter-clockwise by its spring, an insulation roller l 09 on said lever thereupon acting to close a switch I ID in the circuit of an electric motor I00. In this movement the lower end of lever I06 will be disengaged from the tail of a spring urged clutch pawl I03, allowing said pawl to fall into engagement with the driving clutch member I04, driven by motor I00. Pawl I03 is mounted upon a plate I05, this plate being rotated counter-clockwise upon engagement of the clutch. Plate I05 is connected by link I08 ,with a lever 3|6, fulcrumed upon shaft 30l, ro-

tation of the plate serving to reciprocate said lever, the shaft 3M, and a cam'3l8, which operates to effect reciprocatory movement of frame SIS, in known manner.

The wheels of the accumulator 413 are rotated additively upon the return stroke of the actuators BIO, the timed meshing and unmeshing of the accumulator gears being controlled by mechanism disclosed in United States Patent N0.

2,055,623 granted September 29, 1936 to Loring P. Crosman, and entitled Calculating machine.

As shown in that patent, the accumulator pinions 403 (Fig. 1) stand normally in mesh with the segment gears of actuators 6l0, the accumulator shaft 412 being mounted in guide slots of the machine frame so that the accumulator assembly may be moved radially of the actuators, to mesh and unmesh the pinions 403. As shown in Fig. 6, the shaft 472 is adjusted by means of aae evo upon a rock shaft 2. The linkage is held in either of two adjusted positions by means of a toggle spring l l. Fast upon shaft 2 is a plate M9,.having yieldable spring connection fl 'with an arm 5 provided with a lateral flange 22, and pivoted at 33 upon said arm is a switch 6, flange 22 and switch 8 lying in the plane of a roller 1 fixed upon lever 3l6.

In additive operations roller 7 will contact with a cam surface Zl of switch 5 and thereafter with the rear end of flange 22, whereby arm 5 will be raised, thus rocking shaft 2 and linkage Ill, to unmesh the pinions 603 of the accumulator before the actuators are allowed to move. During the forward movement of actuators Bill, arm 5 will be held in raised position by engagement of roller '8 with the lower surface of flange 22. At the end of the forward stroke, roller i will lift the forward end of switch 5 away from a lug 28 of arm 5, and will thereafter move out of contact with the switch, which will return into normal relation with the arm. Upon the return stroke of the operating mechanism, roller i will engage a cam surface 23 of switch 6, restoring arm 5 and the parts M9, M and M2 to original position, remeshing the pinions 303 with the segments to efiect the registration.

The forward movement of slide 66 to engage the clutch will serve to lock key I id in depressed position, by engagement of said slide with a shoulder 56 of the key stem, thus holding the key in depressed position until restoration of slide (it, as hereinafter explained. Forward movement of slide dd also serves to lock other operation keys in raised position. In order to prevent an erroneous operation of the. machine from a rapid or incomplete operation of the motor key, a quick stroke slide ail is provided (Fig. 4), normally held in rearward position, against the tension of a spring, by engagement of a lug it of said slide with the end of slide 1 3. A bail d underlies the stem of key H4, and is displaced thereby when the key is depressed, bringing an edge of the ball into position to engage a shoulder 5b of slide 17. Thus, when key M 2 is properly operated, slide ll will be prevented. from moving forward under the influence of its spring, whereas in case key lll is depressed sumciently to release slide M from roller 63, but is not held long enough to be engaged by slide 3 3, the restoration of the key by its spring 5i will allow the spring ball 69 to'rise out of the path of shoulder 58, and slide dll will move forwardly. The forward movement of slide ll will rock a bell crank lever 52 clockwise as viewed in Fig. 4, bringing one arm of said lever into position to be engaged by a shoulder 53 of slide All, thus locking said slide in partially operated position and leaving latch H2 in engagement with clutch control lever lOGJ Thus misoperation of the machine will be prevented, and the parts will be held in inactive position until slide lll is retracted by a manual operation hereinafter set forth.

In machines of this character, erroneous registrations are sometimes made by the failure of the operator to fully depress one of the digit entering keys 2l5 and as shown means are provided whereby a semi-depressed key will be locked in its semi-depressed position, and

whereby under these circumstances the engagement of the clutch I63, ill l will be prevented.

Each column of digit keys is provided with a latching slide 56 (Figs. 1 and 7), movable forwardly upon depression of a key, by means of a cam surface of the key stem, into engagement with an intermediate locking shoulder 55 or with a full depression locking shoulder 55, slide 5 5 being held in engagement with one or the other of these shoulders by means of a retraction spring 51, Forward movement of slide 56 upon depression of a key 2l5 will bring a beveled end of the slide into register with a notch formed in a transverse slide 58, so that if the key is latched in partially depressed position dide 54 will prevent any considerable transverse movement of slide 58.

Slide 58 engages one arm of a bell crank lever 59, fulcrumed upon a frame plate of the keyboard and having link connection 50 with a pawl 5i carried upon the end of a bell crank lever 62 which is also fulcrumed upon the frame plate. A spring 63 normally holds the parts 58, 59, Ml and M in position in which the pawl El engages a pin 64 fixed in the slide it, and upon release of said slide pressure will be exerted thereby to move slide 58 toward the left. Thus upon operation of the add key ll l, if any of the digit keys j2l5 are locked in partially depressed position, the slide 58 can be moved only a short distance to the left, and pawl 6!, through pin 55, will hold slide ad in partially operated position, wherein roller 53 will rest on top of the slide, but wherein latch H2 will not be disengaged. In this position of the parts key H4 will be locked down and the other operation keys will be inoperative because of the provision of suitable interlocks, to be described hereinafter, and further because of the locking action of slide d ll. Therefore, the machine will remain at rest until the keyboard is manually cleared or until the partially depressed key or keys are fully depressed by the operator. Upon full depression of the keys, slides 56 will be allowed to move rearwardly, into engagement with the shoulders 56 of the keys, freeing slide 58 and the train of mechanism between said slide and the slide M, whereupon the latter slide will be operated by its spring to disengage latch H2 and efiect engagement of the clutch. Slide 15 will also engage a rearward extension of pawl Bl, effecting positive restoration of slide 55.

Near the end of the cycle of operation of the machine, and after actuators 6N) have been brought to rest, means will be operated for releasing the set digit keys M5 and the operation key, for disengaging the clutch and for restoring the control elements to normal position. For this purpose an antifriction roller mounted on a lever 65 (Fig 10) will be engaged by a cam projection of plate "35, and rocked clockwise against tension of a spring 66. A lever Bl is con nected to lever 65 by a spring 55, lever 57 extending upwardly into the path of movement of the lug d5 of slide A l, Displacement of lever 55 by the cam surface of plate m5 will therefore retract slide 6% to and rearwardly beyond its normal position of rest, this extra, rearward movement being utilized to clear the digit key= board. For this purpose a pin 55 on slide 3 3 is 'brought into contact with one arm of a lever 10 (Fig. '7), intermediately fulcrumed upon a frame plate of the keyboard, rocking said lever into contact with a shutter plate fl (see also 1) having lugs engaging shoulders of the slides 54. Slides 56 will thus be moved forward, releasing the keys 2l5 from depressed position and allowing them to be restored by their springs 5|.

Retraction of slide 44 will also unlock the op- -eration key and will allow roller 43 to fall into the key stem (Fig.- 6), lying opposite the looking shoulder 46, will prevent retraction of slide 44 rearward beyond normal position, this being permitted by the tensioning of spring 68 and providing for non-clearing of the digit keyboard.

The keyboard may be manually cleared, and any depressed operation key which has been locked because of an erroneous quick stroke operation may also be released by means of a lever 13 (Fig. 10) ful'crumed on the framing of the machine and extending through the keyboard plate, said lever being adapted to contact and push slide 44 from operated position to its extreme rearward, keyboard clearing position. Manual release of the lever will permit the spring of slide 44 to restore the parts tonormal position.

Subtract and non-add operations Subtract and non-add operations are performed in-response to the depression of a subtract key 214 and a non-add key 215 respectively, these keys controlling the positioning of a. slide 14 (Fig. 2), which in turn controls the adjustment of the switch 6. Slide 14 is held normally under the tension of a spring 15 by engagement of the upper end of a lever 16 with a shoulder of the slide, lever 16 being provided with an anti-friction roller normally engaging .the high point of the cam portion of plate I05.

In the operation of the machine lever 16 will be reciprocated, and slide 14 will be allowed to move forward under the influence of spring 15. In additive operations, however, this forward movement of slide 14 is prevented by engagement of a shoulder 11 of the slide with the bail 49 which has been displaced by the add key H4. There is no shoulder on slide 14 which may contact with the bail 49 of subtract key 214, so that when the subtract key is depressed and the machine opera'ted, slide 14 will move to its extreme forward position. Depression of non-add key .215 will bring its bail 49 into the path of movement of a shoulder 18 of slide 14, to provide for partial forward movement of said slide; Thus slide 14 will be selectively positioned according to the key depressed, the three positions-of the slide being transmitted to switch 6 by means of an arm 19, pivoted to the slide, and held in relation thereto by the spring 15, and a link 80 connecting arm 19 with an arm of the switch.

Depression of the subtract key will thus efmentarily displaced and passed beyond the switch, will be positioned adjacent the surface 24 of the switch, with which it will engage during the return stroke of the operating mechanism, to raise arm 0 and disengage the pinions from the segments before additive movement thereof. During this return movement roller 1 passes beneath flange 22, and near the end of the movement will engage a projection 30 of arm Ii, to restore the parts to normal position.

All of the operation keys are identical in construction, and subtract key 214, aside from the adjustment of switch 6, will provide for the same functioning of the machine as in the case of add key H4.

Non-add key 215 will also provide for the same functioning of the machine except that switch 0 will be rocked only suillciently to bring cam surface 2| parallel with the end of flange 22 of arm I. This will bring the entire switch below the upper line of the flange, except for a proiection of the forward end of the switch above said line. This, however, does not result in any deflection of arm 5, since in the return stroke of the operating mechanism roller 1 will engage a cam surface 23 of the switch, momentarily rocking the same. Therefore, in non-add operations roller 1 will be reciprocated without effecting unmeshing of the pinions 40!, and any amounts subtracted from the accumulator wheels by the actuators during the forward stroke of the operating means will be added back during the return stroke.

Total and sub-total As is usual in machines ofthis type, totals are printed by disengaging the actuators 6l0 from their column latches 2, and from the frame II. and allowing them to move subtractively under the influence of their springs, to

I rotate the accumulator wheels to zero, in which feet rocking of switch 8 clockwise about its pivot position the wheels are held by engagement with appropriate stops, after which the cycling of the machine will effect normal operation of the printing means at the end of the forward stroke of the operating means, whereafter frame 0|! will pick up and return the actuators to normal position.

These and other special functions are effected upon depression of the total key 218, under control of slide 14 and of other spring slides lying beneath the bails 49 of the operating keys.

Depression of total key 218 will release slide 44 and start motor operation, as previously described for the other keys, and it will also allow full movement of slide 14, to provide for subtractive operation-that is to say, the accumulator pinions 403 will be left in mesh during the zeroizing operation, and will be unmeshed before the additive stroke of the actuators H0 is effected.

The zeroizing of the accumulator wheels is effcted by successive operation of the wheels from right to left of the accumulator, as in Patent No. 1,932,013, hereinbefore referred to, this action being controlledby spring operated means. In the present instance, however, it is desired to effect the various adjustments of the controlling mechanisms by power from the motor, and consequently the clutch will be engaged upon depression of the total key, will be allowed a limited driving movement, and then the motor operation will be interrupted to give time for the completion of the zeroizing operation, at the conclusion of which the clutch will be reengaged and.

the cycle of operation completed. For this purpose a slide 8I (Fig. 10), which is locked out of operation by the bails 49 of the add, subtract and non-add keys, will be allowed to operate under the influence of its spring 82, said slide having a pivoted link 83 having pin and slot engagement with a latch 84. Upon forward movement of slide 8| (effected upon forward movement of arm 16) link 83, in the movement thereof about its point of connection with the latch, will have its lower end moved downwardly, tensioning a spring 85 which'will tend to move latch 84 clockwise about its pivotal support. The free end of latch 84 has engagement with a spring pressed arm 96, pivoted upon the machine frame and having an anti-friction roller engaging the cam surface of plate I95. During the first part of the cycle of the operating means the roller of arm 86 will climb to the high point of the cam, rotating arm 86 clockwise and allowing latch 84 to fall into a notch formed in the upper end of said arm. Arm 86 has a rearward extension 81.

which will be held by latch 84 in the path of .ro-

tary movement of the clutch pawl I03, engagement of the pawl with extension 81 serving to disengage the pawl from the driving member I04 of the clutch and to hold it in disengaged position.

Slide 8| also has link connection 88 with an arm I34, pivoted upon the machine frame and provided with a finger I33 which will be brought during the movement of slide BI into contact with the releasing arm 62I of a latch 620, disengaging said latch from a projection 62! secured upon a total segment 6I8, thereby releasing the segment for operation under the influence of a spring 68I. .Segment 6I8 drives a pinion secured on the end of a shaft 60! (Fig. 1), extending across the machine, said shaft being provided with a series of helically disposed pins which will successively trip a series of dogs GI'I, normally securing the actuators 6I8 to frame 6I8. Dogs 6|! are also provided with shoulders normally restraining a series of spring pressed stops 6I3 in negative position. Upon displacement of a dog (ill the related stop 6I3 will be released, being brought by its spring into the path of movement of a zero stop 45'! of the related accumulator Wheel. During this preliminary setting of the total controls, the column latches 2I4 will also be released, in the manner hereinafter described, so that actuators BID upon successive release from the frame 6I6 will be moved by the springs to rotate the related accumulator wheels to zero.

Upon complete rotation of shaft 601, the projection 62! of segment 6I8 will contact with a rearward extension of the arm'BZI, rocking the forward end of said arm out of contact with the finger I33, and allowing latch 620 to move under influence of its spring into position to reengage the extension 62'! upon restoration of segment 6I8. Also, at this time, a pin 89, fixed in segment 6I8, will engage a depending arm of latch 84, rocking said latch out of engagement with arm 85, whereupon said arm will be rotated counter-clockwise by its spring to move the extension 81 out of restraining contact with clutch pawl I03. Thereupon pawl I83 will reengage with driving member I04 and the operating cycle of the machine will be resumed. During the forward stroke of the operating means, segment 6I8 will be restored to normal position and reengaged by its latch 620, this restoring means being well known and not illustrated in the present disclosure.

In order that the keyboard may be free for the setting up of an item during the total taking operation, the index bars 6I5 are designed to be shifted laterally out of position of engagement with the key stems. A similar arrangement was proposed in United States Patent No. 2,087,182, issued on July 13, 1937 to Loring P. Crosman, entitled Listing adding machines. However, the means of the present disclosure are of improved construction, and are designed to permit setting of the digit keys during any portion of the totalizing operation.

The index bars BIS are supportednear their ends in sliding plates 98 (Fig. 5), urged toward the right hand side of the machine by springs 9|. The ends of the bars are engaged by a pair of bell crank levers 92, these levers being provided with shoulders engaging lugs 93 of a slide 94. Slide 94 lies parallel to the slides 14 and 8|, and is likewise reciprocated by the operation of lever I6, being moved toward the front of the machine under the influence of the springs 9|. Bails 49 of the add, subtract, and non-add keys are depressible into position in front of shoulders 95 (Fig. 6) of the slide, to prevent operation thereof. Normally the lever 16, through slide 94, will serve to hold the index bars M5 in normal relation to the digit keys 2I5 and to the zero latches 2 I4, as seen in Fig. 5. Upon forward movement of slide 94, springs 9I will move plates and index bars 6I5 toward the right, out of position of contact with the keys and also out ofcontact with the zero latches 2I4. The plates 90 operate individually, so that there can be no jamming of the parts due to twisting action.

In order that amounts set on the keyboard will not be cleared during the totaling operation, the bail 49 of the total key is provided with an extension 96 (Figs. 2 and 3) which will be held by the key in position to engage a shoulder 9'! of slide 44 and prevent movement of said slide rearward beyond its normal position, thus preventing the clearing of the keyboard, as previously explained.

Means are also provided whereby partial depression of a digit key 2 I 5 will not prevent a total taking operation, but wherein the parts will remain in position to prevent subsequent operation of the other-keys until the keyboard has been cleared or the digit keys properly depressed.

This means is shown as associated with a series of interlocking members between the operation keys 218, 213, H4, 214 and 215 (Fig. 8). The Interlocking means comprises a series of plates 98 located each between two adjacent operating keys, and having shoulders enga'geable by the key stems. As seen in Fig. 6, the portions of the key stems engaged by plates 98 are wedge shaped, so that in the depression of any of the operating keys the two adjacent plates 98 will be moved or held in opposite directions, against the stems of the next adjacent keys.

It will be obvious, therefore, that the plate lying between sub-total key 273 and add key H4 will be moved or held in forward position upon depression of the add key and in rearward position upon depression of the total key 278 or subtotal key 213. A pin 99 is fixed in this plate 98, and projects downwardly into engagement with a slot of the bell crank lever 62 hereinbefore referred to. During operations controlled by the add, subtract or non-add keys the pin 99 will lie in the position illustrated in Fig. 7, and pawl 6| will act to lock slide 44. Upon depression of -the total or sub-total key, however, rearward movement of pin 99 will rock bell crank lever 82 clockwise, withdrawing pawl 61 from position of contact with the pin 64 of slide M, so that the slide will not be locked, should a key 2l5 be partially depressed, until after the release of the total or sub-total key. In a subsequent operation of the machine by key H4, 214 or 215 the pin 99 and bell crank lever 62 will remain in the position illustrated, and tripping of the clutch will be prevented.

Sub-total key 213 operates precisely in the manner of total key 218, except that slide 14 is held in its partially operated position by engagement of the bail 49 with a shoulder H of the slide. Thus switch 6 is held in the same position as that assumed in non-add operations, whereby the total, subtracted from the accumulator wheels, is restored thereto during the return stroke of the operating mechanism.

It is intended. when the clutch is disengaged by contact of clutch pawl I03 with lever I06 or with the extension 81 of arm 86, that rebound of the driven parts will be resisted by the rollers of arms 65 and T6, and in order to permit effective checking action the usual heavy spring I40 (Fig. 9),

used to assist in smoothing the load on the motor,

is provided with lost motion connections with its anchor 14! and with the arm I42 of shaft Bill.

I claim:

In a motor driven listing register having a driving train, a clutch in said train, printing means operable by said train, an accumulator, spring actuated means for zeroizing said accumulator, and a totalkey operable to engage the clutch; a total control member movable under control of the driving train upon operation of the total key, means operable by said member to initiate operation of the Zeroizing means, and a member displaceable by the total control member to disengage the clutch, said zeroizing means acting to restore the displaceable member and thereby to reengage the clutch and effect printing.
